15 Claims. (01. 140-71) This invention relates to metallic wool manufactures and more particularly to a metallic wool fabric suitable for binding pressing pads and for sundry other purposes and the method of making the same.

Metallic wool has long been'used as a padding material for pressing machines for which it is well adapted, because of its elasticity, non-absorbent qualities and resistance to deterioration l0 under influence of heat and moisture. It has been customary to provide a marginal binding of asbestos cloth or other non-metallic fabric upon such" pressing pads. It is, however, desirable to have all parts of the pad of uniform character and material, and hence the present form of metallic wool fabric affords a desirable substitute for such non-metallic binding material; It is to be understood, however, that the metallic wool fabrie forming the subject matter hereof is not limited to such application, but is applicable to many other purposes, in arts far removed from pressing pads. Its association with pressing pads in the present disclosure is for illustrative purposes and with no intent to unduly limit the invention. a

' The object of the invention is to provide metallic wool fabric in strip, sheet or ribbon form of any desired width which will be strong, durable, flexible, emcient in use, substantially unequivalents, as hereinafter described and. set

forth in the claims.

In the drawing wherein is shown the preferred 40 but obviously not necessarily theonly form of embodiment of the invention, Fig. l is a perspective view of a conventional form of metallic wool pad having thereon a marginal binding of metallic wool fabric forming the subject matter 45 hereof. Fig. 2 is a perspective view of a portion of a fabricated metallic wool strip or ribbon. Fig. 3 is a perspective view illustrating a method of manufacture of such fabric.

Like parts are indicated by similar characters 50 of reference throughout the several views.

Referring to the drawing, l is a metallic wool pressing pad such as is used upon steam garmentpressing machines. The pad I may be of tangled or felted metallic wool, or it may consist of metallic .wool fabric comprisingr'ovings of metallic wool systematically arranged in substantially parallel relation and united by transverse tie wires which may be either knitted or woven or otherwise interlaced about the metallic wool strands or rovings. Such fabricated metallic wool padding material is available upon the market and its particular construction and character forms no part per se of the present invention.

Disposed about the margin of the pad I, as illustrated in Fig. 1, is a binding strip or ribbon 2, also of metallic wool material, which in combination with a metallic wool pad or apart therefrom, and its method of manufacture, form the subject matter hereof. The strip or ribbon 2 used to bind the pad I comprises longitudinal strands 3 of substantially parallel metallic wool fibers arranged in a relatively fiat series or approximately common plane. Disposed transversely of the longitudinal material 3 are transverse strands 4 of metallic wool material, also arranged in substantially'parallel relation. However, inlieu of being interwoven or interlaced with the longitudinal'strands, the transverse material is wrapped around the assembly of longitudinal strands, thereby affording a continuation of transversely disposed transverse material on opposite sides of the longitudinal material throughout the extent of the fabric. is no directional interlacing or weaving of the respective materials, nevertheless the fibers of the longitudinal and transverse strandswill intertangle or interlock with each other sufliciently While there I to retain the assembly of transversely disposed.

strands in a unitary strip or ribbon form.

The longitudinal-and transverse strands may be'of the same material and of the same or different degree" of fineness-,or the longitudinal and the transverse strands maycomprise fibers or shavings of different metals and whether the same or different metals, may be of different grades or character. I

In the manufactureof the metallic wool fabric sisting of an intermediate stratum of substantially longitudinally disposed fibers and exterior strata of transversely disposed fibers on opposite sides of the longitudinal fibers. Such ribbon may be made of different widths or of different thickness by correspondingly varying the quantity of material and the degree of tightness with which the transverse material is wrapped around the longitudinal strands. The pressing and manipulation of the material not only reduces it to a thin fiat sheet form but also effects an interlocking or felting of the transversely disposed fibers with each other.

While as illustrated the resulting fabric is useful and desirable for binding pressing pads of metallic wool and the like, it is also applicable to a wide variety of other purposes, such as filter sheets, cover sheets and the fabric when out into sections and superposed one upon another may be formed into pressing pads such as shown at 1. Such laminated construction facilitates the formation of contoured form retaining pads.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute, the invention has been described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise the preferred form of several modes of putting the invention into effect, and the invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the appended claims.

Having thus described my invention, I claim:

1. A pressing pad and a marginal binding strip therefor of metallic wool material comprising a separately formed flat binding strip of transversely arranged interfelted strands of metallic wool material'for enclosing the margins of the pad when secured thereto.

2. A metallic wool pressing pad and a marginal binding strip therefor of metallic wool material comprising superposed interfelted strata of metallic fibers formed into a continuous strip of metallic'wool fabric secured about the margins of the pad and confined thereto.

3. A metallic wool pressing pad and a marginal binding strip therefor formed of transversely disposed interfeltedstrands of metallic wool material secured about the margins of the pad and confined thereto.

4. As an article of manufacture, a sheet fabric comprising a single flat layer of longitudinal and double layer of transverse strands of metallic wool fibers, the transverse fibers being helically disposed in contacting convolutions extending exteriorly about opposite sides of the longitudinal strands.

5. As an article of manufacture, a thin fiat flexible metallic wool fabric comprising a single layerv of longitudinally disposed fibers of indeterlayers extending continuously on opposite sides of the layer of longitudinal fibers.

6. As an article of manufacture, a thin flat ribbon-like strip of flexible metallic wool fabric comprising a single layer of longitudinally disposed metallic fibers of indeterminate length and transversely disposed rovings of metallic wool fibers contacting with each other and interfelted with the longitudinal fibers, the assembly being compressed into sheet formation.

7. The herein described method of manufacturing metallic wool fabric consisting in progressively winding successive contacting turns of a roving of metallic wool material transversely about a longitudinal roving of metallic wool material and subsequently compressing the assembly into flat sheet formation wherein the transverse and longitudinal strands of material comprising the respective rovings are interfelted with each other.
